International calling codes, also known as country codes or dialing codes, are numerical prefixes used to dial telephone numbers in different countries. These codes are assigned by the International Telecommunication Union (ITU) and are essential for making international calls.
When making an international call, you typically dial: Exit code + Country code + Area code + Local number. For example, to call China from the US: 011 + 86 + area code + local number.
The country code +1 is shared by the United States, Canada, and several Caribbean nations under the North American Numbering Plan (NANP). Most other countries have unique codes ranging from +20 (Egypt) to +998 (Uzbekistan).
